Practice exam 4 Q9

Category: CSAA – Design Resilient Architectures

A client is hosting their company website on a cluster of web servers that are behind a public-facing load balancer. The client also uses Amazon Route 53 to manage their public DNS.

How should the client configure the DNS zone apex record to point to the load balancer?

Answer: Create an A record aliased to the load balancer DNS name.

Don’t like this question, the answer just happens to be the “most correct” even though it technically isn’t correct either because it doesnt specify the load balancer is an AWS one, it just says “public-facing”. Are we supposed to assume it’s an AWS one? R53 cant do A+alias records for a non-AWS resources correct?

Hi hellojellojw,

Thanks for your feedback.

You’re correct in your understanding. Amazon Route 53 does support alias records, which allow you to map your zone apex (e.g., example.com) DNS name to your load balancer DNS name. However, this is specifically for AWS resources. If the load balancer is not an AWS resource, Route 53 wouldn’t be able to create an A record aliased to the load balancer DNS name.

It appears that the question assumes the load balancer is an AWS resource, although it could have been stated more clearly for better understanding. We have taken note of this feedback and will make necessary updates to ensure that the information provided is more explicit. The changes will be reflected on the portal as soon as possible.

Hi, so I would just like to point out that I do not see a change in the question to state the ALB is aws so now I am wondering whether these questions that I purchased in 2022 are updated at all??? I mean, it says im doing the AWS Certified Solutions Architect Associate Prac Exams SAA-C03 2024 (however i purchased this in 2022 and its valid for 3 yrs), however as i mentioned, the question still says Application Load Balance and not AWS Application Load Balancer.

Do you guys actually take the feedback and make the changes?
